摘要
实验利用紫外-可见吸收光谱研究了主客体掺杂型非线性聚合物薄膜(DR1/PMMA)的极化条件与生色团取向有序度、弛豫特性之间的关系。结果表明,在不改变其它条件的情况下,随着极化电压的增加,聚合物薄膜的极化取向有序度、抗弛豫性能得到逐步增强;而在接近于该聚合物薄膜的玻璃化温度情况下进行极化,有助于获得更好的取向有序度和抗弛豫性能。同时实验发现,环境湿度的降低则能显著地增强薄膜偶极子的取向稳定性。
Taking the guest-host DR1/PMMA films for example, the poling condition on the order parameter and relaxation of the films were studied with UV-Vis spectrum. The results indicate that by poling polymer films with a certain condition, the order parameter and oriented stability improved with the rise of poling voltage and reached the saturation gradually, while the order parameter and oriented stability are better when the poling temperature approaches the glass transition temperature of DR1/PMMA film. Furthermore, the oriented stability is remarkably enhanced by reducing the relative humidity of the poling environment.
